Hi.

You can link your graph to a javascript action, here you can find more documentation about it:

https://kb.fusioncharts.com/questions/459/What+is+a+Drill-down+chart%3F#javascript


When you are creating the XML you cand add the javascript action.

JavaScript: prefix :
provide single or multiple JavaScript functions or statements after JavaScript: prefix. e.g.,

<set label='USA' value='235' link="JavaScript:  CallOSAction();"/>

Create a hidden button  that executes the screen  action (do not forget to give a name to your button)


You can achive what you want, if, when you call the JS action and click the hidden button, this javascript code would look something like :

function CallOSAction(){
    osjs(function($) {
         $('#'+ElemId).click();
    });    

}

Cheers
